I'm using Amadeus Pro Version 2.2.2 (1640) on an iMac 5K with 10.11.2.

I recorded a ~98 minute session for my students. It was fine - I edited it and saved it in standard .amad format.

Later, I came back to it to save it out to mp3. Three things were done or happened:
1) I had to reboot my USB 3 hub which the mic was plugged to. Amadeus gave me notice that the "device had died". I closed the message and everything seemed fine.

2) I set the information under "Sound -> Show Sound Info," including adding a graphic. It appeared still fine in the waveform editor, though I did not listen.

3) I saved again. It still appeared fine.

4) I used Tracks -> Convert Track to Mono

After #4, there was nothing but a flatline with apparently 60hz buzz.

5) I hit "undo". It brought back two channels of flatline with buzz. No sounds left!!!!

6) I closed it promptly with NO save. (I've learned my lesson before...)

7) Re-opened... two channels of flatline with just buzz

So, my questions are:

1) Is there any way to recover my now lost/corrupt sound file? I need to deliver the lesson tomorrow.

2) What did I do "wrong" that I can avoid so this will never happen again?

Thanks for your response. I've PM'd you the link for the file. I guess I will start re-recording now. I tried everything I could, I can't get it back.

Here are answers to your questions:
1. Did I quit Amadeus? A: I don't believe so. It was a busy day, so there's a small chance that I did, but I think that I kept it running the whole time.

2. It was an .amad file the whole time. I never converted to mp3, that is always my last step after conversion to mono, to "save a copy as..." mp3. I always keep the original in .amad in case I want to go back and edit.

Dear Morgan, the only explanation I can imagine is that the disk containing the temporary file with the recording got unmounted at some point during the session, causing Amadeus Pro to lose track of the data. You mention that you had to reboot your USB hub. Did this hub have an external hard drive attached and is it possible that Amadeus Pro was using that drive to store its temporary files?

If that was the problem, you may be able to recover the recording by plugging in that drive and launching Amadeus Pro. It should scan for temporary files and, if it finds any, it should tell you so and place them in the trash bin from where you can recover them.

One way to avoid this in the future is to force Amadeus Pro to use your internal drive for its temporary files, you can specify this in the preferences. Regards,

Thanks for your response. There was some weirdness with the USB 3 hub, one of my disks had become unresponsive, and that's why I power cycled it. That temporarily unmounted/re-mounted several disks.

However, it's strange that the temp files would have been on these other disks. My home directory is on the boot drive, so I don't see any reason that Amadeus would put temp files on another mounted volume...? I saved it to my Dropbox folder, which is also on my boot drive.

When I re-mounted the drives, it didn't find anything new. I suppose I could go look for it, but I already re-recorded it.

Anyway, this is the first real problem like this in years of using Amadeus, hopefully just a one-time occurrence.
